Hello Shaun,
1) dahdi-linux-complete-2.2.0.2+2.2.0 , is generatiing 1K int/s after
patches..
2) Looking in 2.2.1 code, i see to wct4xxp.c the alarmdebounce set in
2500 and in 2.2.0 the alarmdebounce seted to 0,
I load the module with alarmdebouce=0 paramter => the interrupts are up
to 1000 int/s
After this, I test all versions until dahdi-linux-complete-2.6.0+2.6.0
cd version
make distclean
make
make install
/etc/init.d/dahdi stop ;sleep 3; modprobe dahdi; modprobe wct4xxp
debug=1 alarmdebounce=0 ; dahdi_cfg
.itop => to see interrupts.
always are 1000 ints/s
I not touch in losalarmdebounce=0 aisalarmdebounce=0 yelalarmdebounce=0
module paramters.
3) Can you explain-me aboute how the alarmdebounce and its variants (
LOS, YEL, etcc ) impacts the system perfomance and how
can i fine tune this ?
Regards,
Marcio Gomes

Hello Shaun,
I take this approach :
- zaptel 1.2.XX , 1.4.XX I can see interrupts working , I made some
patches to compile in 2.6.32 kernel tree.
- dahdi 2.0.0 to dahdi-2.2.0, I can see interrupts working, I made
some patches to compile in 2.6.32 kernel tree
- This "itop" from 2.2.0 tree :
IRQs/Second
Device (IRQ) CPU0 CPU1
TOTAL
rtc0 ( 8): 0
0 0
i8042 ( 1): 0
0 0
eth0 ( 28): 3
3 6
timer ( 0): 435 566
1001
ata_piix, ata_piix ( 19): 2
1 3
pata_jmicron ( 16): 0
0 0
cascade ( 2): 0
0 0
wct4xxp ( 20): 566 435
1001
As you can see, I am having 1K int/s
- My patches are related to add #include <linux/sched.c> in
dahdi-base.c , wct4xxp.c and wctdm.c , and comment out the lines
relative to others drivers ( I only needs wcfxo, wctdm and wct4xxp
to this box )
- 2.2.1 and greater -> Compiles without patches, but not working,
int/s = 0
I do not knows the main changes from 2.2.0 to to 2.2.1 dahdi-tree ,
but it is clear to me that problems are in this changes. I can goes up
and down between versions
with same issues, I do this because initially suspected from da dead
lock in hardware create for some tests I have do.

News from Zaptel..
I patch the last zaptel.1.2.27 to compiles in 2.6.33 kernels
series.... Surprise !!!!!!
20: 68011 71871 IO-APIC-fasteoi wct4xxp
in zttool the spans are RED, all is working with pre 1.4 zaptel and
dahdi.
The problems are in changes between zaptel.1.2.X and zaptel.1.4.X.
I thinking now that is an old issue added from 1.2 to 1.4 branches
and sucessivily to dahdi branches,
and I lost something in past.
But I want go to asterisk 1.8 and greater with new drivers , Can
anyone help me in this ?

Hello All,
I really not understand de APIC changes in IO-APIC-XXXX and the
greater 100 Interrupt numbers in old setups.. can you help me ?
I forget to say,
In production BOX, I "only" do a linux -R newconfig && reboot ,
slots , hardware, setup, etc.. is the same.. no changes. It's give
me a confirmation about it is not a hardware issue, the only changes
are in software.
In the development box, a hardware problem iss possible, I will make
a copy of the working software and put in it to clarify this
doubt.

Marcio Gomes
